Question

I have a $content with

<div class="slidesWrap">
   <div class="slidesСontainer">
      <div class="myclass"> 
        ...
      </div>
      <div class="myclass">
        ...
      </div>
      ...
      ...
      <div class="myclass">
        ...
      </div>
   </div>
   <div class="nav">
      ...
   </div>
</div>
some other text here, <p></p> bla-bla-bla

I would like to remove via PHP all the divs with class=”myclass” except the first one, and add another div instead of others, so that the result is:

<div class="slidesWrap">
   <div class="slidesСontainer">
      <div class="myclass"> 
        ...
      </div>
      <div>Check all divs <a href="myurl">here</a></div>
   </div>
   <div class="nav">
      ...
   </div>
</div>
some other text here, <p></p> bla-bla-bla

Would be grateful if someone can point me a solution.

UDATE2:

some similar question here
from that I came up with the following test code:

$content = '<div class="slidesWrap">
   <div class="slidesСontainer">
      <div class="myclass">
      </div>
      <div class="myclass">
      </div>
      <div class="myclass">
      </div>
   </div>
   <div class="nav">
  </div>
  </div>
 some other text here, <p></p> bla-bla-bla';

$dom = new DOMDocument();
$dom->loadHtml($content);

$xpath = new DOMXPath($dom);
foreach ($xpath->query('//*[@class="myClass" and position()>1]') as $liNode) {
    $liNode->parentNode->removeChild($liNode); 
}

echo $dom->saveXml($dom->documentElement);

Any ideas where I can test it?

Here is what you are looking for (similar to your edit, but it removes the added html tags):

$doc = new DOMDocument();
$doc->loadHTML($content);

$xp = new DOMXpath($doc);
$elements = $xp->query("//div[@class='myclass']");

if($elements->length > 1)
{
    $newElem = $doc->createElement("div");
    $newElem->appendChild($doc->createTextNode("Check all divs "));
    $newElemLink = $newElem->appendChild($doc->createElement("a"));
    $newElemLink->setAttribute("href", "myurl");
    $newElemLink->appendChild($doc->createTextNode("here"));

    $elements->item(1)->parentNode->replaceChild($newElem, $elements->item(1));     

    for($i = $elements->length - 1; $i > 1 ; $i--)
    {
        $elements->item($i)->parentNode->removeChild($elements->item($i));
    }
}

echo $doc->saveXML($doc->getElementsByTagName('div')->item(0));
